SHADE-HOLDING DEVICE.

Specification of Letters Patent.

Patented Nov. 19, 1918.

Application filed February 7, 1916. Serial No. 76,675.

To all whom it may concern:

Be it known that I, REUBEN B. BENJAMIN, a citiZen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Shadellolding Devices, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawing, forming a part of this specification.

My invention relates to shade holding devices.

One of the objects of my invention is to provide such a device which will be simple in construction, eflicient in'use and cheap to manufacture, and which will enable shades of different types and dimensions to be properly secured with respect to receptacles of diflerent types.

Further objects will appear from the detailed description to follow taken in connection with the appended claims.

In the drawings in which I have shown several embodiments of my invention Figure 1 is a vertical axial section of a lamp shade and shade holding means; I

Fig. 2 is a section On the line 22 of F ig. 1;

Fig. 3 is an axial section showing a different form of shade holding means;

Fig. 4 is a perspective view ofthe shade holder of Fig. 3;

Fig. 5 is a plan view of the shade holder of Fig. 3; and

Fig. 6 is an axial section other form of holder.

Referring in detail to Figs. 1 and 2 of the drawing the lamp shade 10 comprises a bowl shaped reflecting portion 11 and a sheet metal neck portion 12 permanently secured to the bowl portion. A threaded connecting ring 13 is provided for securing the shade in proper position with respect to a lamp socket and a spring retaining member 14 is provided to hold the connecting .ring in position. The neck portion 12 of the shade is flanged over at 15 inside of the bowl portion forming a permanent connection and is headed inwardly at 16 to provide a hole for the screws of the three-screw type of shade holder, and has an inwardly extending showing still anflange 17 at its upper end which forms a finish for the neck of the shade. This flange 17 extends farther in than the bead 16. The connecting ring 13 comprises a threaded portion 18 for screwing onto a threaded support, an enlarged portion 19 which extends through the opening in the neck 12 and a flange portion 20 which engages the flange 17 This flange 20 is small enough to permit the ring 13 to be put in position from the inside of the shade, the flange being small enough to pass the head 16 but not small enough to pass through the opening in the flange 17. The retaining member 14 is a U-shaped spring which may be of wire and comprises two parallel arms 21 and a connecting portion 22. The corners or angle portions 23 of the retaining member and the free ends 24 of the arms 21 engage the neck portion 12 above the bead 16; the tension in the spring being such as to tend to force these parts outwardly, and the intermediate parts of the arms 21 and the portion 22 engage the flange 20 of the threaded ring 13 to hold the threaded ring in posi tion with respect to the neck. For preventing relative rotation between the threaded ring 13 and the neck portion 12 the flange 17 may be notched as indicated at 25, and the connecting ring may be a portion struck up therefrom as indicated at 26 to engage the notch 25. The ring 13 may be screwed onto a threaded supporting member 27 which may or may not be integral with the lamp socket.

To secure the shade to the socket the ring 13 is dropped into the neck 12, the flange 20 engaging the flange 1'7. The retaining member 14 is then sprung into place to hold the flange 20 against the flange 17. The ring 13 is then screwed onto the threaded support 27. Vhen screwing this on the shade itself may be used as a handle, the projection 26 and notch 25 preventing relative rotation between the shade and ring.

In the form shown in F igs. 3, 4 and 5 the shade 10 may be the same as in Figs, 1 and 2. A spring connecting member 28 engages the neck 12 and secures the shade to the socket 29. This connecting member 28 may be formed of a single piece of stamped sheet metal bent to a substantially triangular shape to form two arms 30 having their ends notched as indicated at 31 and a portion 32 connecting the arms 30. The corners 33 of the connecting members are also notched as indicated at 34 and the edge of the flange 17 engages within the notches 31 and 34. The intermediate portions of the arms 30 and lie within the notches 31.

connecting portion 32 are stamped or beaded.

using this holder the connecting-member 2Q g is positioned so that the edge of the flange 17 will enter the notches 3% and the arms 30 are then, sprung inwardly as indicated in dotted lines in Fig. 5 until the ends of these arms can be moved down so that the notches 31 are opposite the edge of the flange 17. The connecting member is then allowed to expand so that the edge of the flange 17 will The connecting member 28 is then slipped in place on the socket until the bead 37 engages the beads 35 of the connecting member.

In the form shown in Fig. (3 the shade 12 may be the same as in Figs. 3, 1 and 5 and the connecting member e0 may alsobe the same as in Figs. 8. 4 and .5, except that the notches 31 and 3 1 are dispensed With. In this form, however. the ends of the arms of the connecting 'member and the corners of the connecting member engage the nee-k of the shade below the flange 17 and above the bead 16.

Having thus described my invention what I claim as new and desire to secure by Letters Patent 1s 1. The combination with a shade, a lamp socket, means for holding said shade in position with respect to said socket, said shade comprising an annular portion and said supporting means comprising an integral spring member bent to form two arms each having one free end and a portion connecting the other ends of said arms with each other, the free ends of said arms and the angles where said connecting portion joins said arms inter-engaging with the inner surface of said annular portion.

2. The combination with a shade, and a lamp socket, of means for holding said shade in position with respect to said socket, said shade comprising an annular portion and said supporting means comprising an integralibent spring member the angles .of' which mterengage with the inner surface of said annular portion. and a threaded ring held in place by said spring member.

3. The combinatlon with a shade, a lamp socket, means for holdlng sald shade 1n position with respect to said socket, said shade comprising an annular portion and said supporting means comprising an integral spring member bent to form two arms each having one free end and a portion connecting the other ends of said arms with each other, the free ends of said arms and the angles where sald connecting portion joins said arms inter-engaging with the inner surface of said annular portlon, and a threaded ring having a flange portion engaged and held in place by said arms and connecting portion.

4. The combination with a lamp shade having a neck having an annular outwardly beaded portion, and an annular inwardly extending flange portion, of a threaded ring having an annular outwardly extending flange portion engaging the lower face of said first flange portion and a spring member having portions extending within said beaded portion and portions engaging said outwardly extending flange to hold said ring in place.

5. The combination with a lamp shade having a neck havingan annular outwardly beaded portion, and an annular inwardly extending flangeportion. of a threaded ring having an annular outwardly extending flange portion engaging the lower face of said first flange portion and an integral spring member bent to form'two arms each having one free end and a portion connecting the other ends of said arms. the angles where said connecting portion joins said arms interengaging with said annular portion, and the intermediate portions of said arms and said connecting portionengaging said socket.

In witness whereof I have hereunto subscribed my name in the presence of two witnesses. REUBEN B BENJAMIN.
